This question is directed at Bruce, but if anyone else has a contribution, feel free to speak.
Bruce, What is the best way to measure the reverse isolation of an amplifier (particularly a buffer amplifier for a 10 MHz reference), when it is expected to be in the order of 100 dB or more? Feeding the output with a known signal and measuring at the input with a spectrum analyzer comes to mind, but I am sure there must be something wrong with that technique, it sounds too simple. The presence of a signal at the input (or not) may affect the operating point of the amplifier, so measuring from output to input without such signal may not give a true result.
